I go through pretty much the same issues with my 2 1/2 & 1 1/2 year olds, The 1 1/2 year old recently came out of her crib because she was climbing out & scared to death of the crib tent, anyhow, she started sleeping in the toddler bed & did fine for the first month but then my husband made the mistake of letting her stay up later one night with her 2 1/2 year old sister & him because they were watching a movie, anyhow, long story short after she had been easy to lay down in her bed & fall asleep on her own for over a year, she now thinks that she has to lay on the couch with her daddy & watch tv until she falls asleep. With our 2 1/2 year old we started out doing the family bed thing, and had planned on her sleeping in her own bed around 1, but needless to say she wasnt ready to leave the family bed, so she has recently started falling asleep, sleeping through the night, and going to sleep by herself if we let her sleep on the couch. As before it was a battle and I had to lay down with her in my bed until she fell asleep & then put her in her bed after she fell asleep & she would get up all through the night & get into my bed. I know it may not sound like great parenting, but for the sake of sleep I let my 2 sleep on the couches if that is where they will sleep alone & fall asleep without a battle.
